3.2.19 is the last version of the old Cave3D.
As of May 1st, 2020 the old Cave3D code is frozen, and it is not
updated any more.
Version 3.2.x is TdManager ready.
TdManager is the TopoDroid cave project manager, integrated in the TopoDroid app.
The apk 3.1.66 is built with Android sdk-26 as mandatory on Google Play from Nov. 1st 2018.
The apk 3.1.42 has a new model wall reconstruction implementing the powercrust algorithm.
This approach is suitable only for dense set of splays ( ie, when the distance of a splay endpoint to the
nearby splay endpoints is less than the passage minumum width ).
The algorithm is implemented natively: supported archs are arm and arm-v7 .
With version 3.1.4 the namespace has changed to com.topodroid.
If you have previous install of Cave3D, clear the app data saved in system and
uninstall the app before installing the new version.
